Hinged faceplate

ABSTRACT

A faceplate for mounting to an outlet box located behind a wall has an upper portion and a lower portion. The upper portion is pivotally attached to the lower portion so that it may be swung out from the wall to permit access to the rear thereof and to the outlet box. The front face of the faceplate has one or more openings therein into which both electrical and optical fiber type couplers may be fitted. The front face of the faceplate has tracks formed thereon for mounting a protective hood, and the rear face of the faceplate has an aperture therein for receiving and mounting a fiber or wire storage member.

FIELD OF INVENTION

This invention relates to outlets for communication type cables and moreparticularly to an outlet for connecting multiple types of electricaland optical fiber cables to a standard wall mounted electrical box.

BACKGROUND OF THE INVENTION

In present day communications involving signal transmittingcommunication lines, several standardized interface connectingarrangements have been adopted for establishing electrical connectionsto the lines. One such interface is the miniature or modular jack, whichhas been adopted by the U.S. Federal Communications Commission as thestandard connector for connecting telephone equipment to communications,i.e., telephone, lines. This jack, however, comes in different versions,depending upon the number of electrical contacts to be made, e.g., four,six, or eight. In addition, other connectors, such as coaxialconnectors, exist for equipment other than telephones that share thesame location at a customer's premises, but do not share the sameinterface standard. Because a large number of such non-standardconnector types exists, individual and separate housings and wall platesare necessary to enable the customer to connect all of his or hercommunications equipment to the proper incoming and outgoingcommunications lines.

In U.S. Pat. No. 4,261,633, there is shown a jack frame molded into awall plate as an integral part thereof. However, this arrangement hasthe disadvantage, as suggested hereinbefore, of requiting a differentwall plate for each different jack, different plates being needed forjacks that differ from each other only slightly. U.S. Pat. No. 4,859,201represents an improvement over the '633 patent in that it canaccommodate a number of jack outlets where, conceivably, the jacks couldbe different from each other. However, the embodiments disclosed in thatpatent do not provide for easy and quick attachment and removal of thejacks to and from the wall plate. U.S. Pat. No. 5,096,439 of Arnett isdirected to an arrangement for mounting a number of jacks to a singlewall plate with a simple and convenient arrangement for attaching andreleasing the jacks to and from the wall plate. Thus, it can beappreciated that the prior art, in the electrical communications area,has progressed to the point of accommodating multiple jacks in a singlewall plate. However, there does not appear to be, in the prior art, anyarrangement for accommodating both electrical wires and optical fibersin a single flush mounted wall plate. There are, in the prior art,arrangements using both electrical and optical connections. However,these arrangements are not flush mounted, generally requiring specialboxes for containing the connections, which do not provide ready andeasy access to the connectors. In part, this is a consequence of thevery special handling and connecting limitations for optical fiber.

Optical fiber cables, more particularly single buffered fibers encasedin a protective member, require extreme care in handling and inconnecting, as well as positioning and storing. The fiber cannot bewound or bent to a radius less than a prescribed minimum without theoccurrence of microcracks. Thus, it is important that some form ofstrain relief be used in routing the fiber. Further, it is desirablethat the fiber be guided and supported to eliminate any loose fiber sagsor loops that could, possibly, be inadvertently snagged or twisted,thereby risking damage to the fiber. In addition, the connection of thefiber to another fiber or to apparatus requires that the connector becapable of joining two optical fiber ends with a minimum of insertionloss and it must be mechanically stable while providing adequateprotection to the junction between the fibers. There are, in the presentstate of the art, numerous types of optical fiber connectors in use,which are, for the most part, incompatible with each other and whichvary as to size, shape and mode of connection. This problem is treatedin U.S. Pat. Nos. 5,274,729 of King et al. and 5,238,426 of Arnett inthe context of universal patch panels. In the King et al. patent, thepatch panel has a plurality of differently sized and shaped openings foraccommodating the mounting hardware, by means of build-outs, of aplurality of different optical connectors. The Arnett arrangement has apatch panel or plate having a plurality of substantially identicalopenings therein in which are mounted adapters for different types ofoptical couplers as well as electrical couplers. Neither patent dealswith wall plates and the additional problems attendant thereto.

The standard wall plate functions as a cover for the commonly used NEMA(National Electrical Manufacturers Association) electrical outlet box,generally mounted to the rear of the wall. As such, the wall plategenerally has one or more electrical jacks, with connecting wires beingstored in the outlet box or passing therethrough, where necessary. Suchan assembly is compact, efficient, and simple to use, the customer, forexample, having only to plug a connector jack into its receptacle on thefaceplate to complete the connection. However, the prior art, for themost part, does not address making the faceplate universal, i.e.,accommodative of both electrical and optical fiber connectors, to thesame degree that the universal patch panel has been fabricated. Thisstems, in part, from the care with which the optical fiber must betreated.

The care exercised in handling fibers is embodied, for example, in theSC connector, the general industry acceptance of which is increasingrapidly. Such a connector for connecting buffered fibers is shown anddescribed in U.S. Pat. No. 5,212,752 of Stephenson, et al. An SCconnector includes a ferrule assembly including a barrel having a collarat one end and an optical fiber terminating ferrule projecting from thebarrel. The ferrule assembly is disposed in a plug frame such that anend portion of the ferrule projects from one end of the frame. The plugframe is configured to snap lock into a grip member, and the grip isinserted into one side of the coupler and locked thereto, while thecorresponding grip of another SC connector is inserted into the otherside of the coupler and locked. The coupler is dimensional such thatwhen the two connectors are inserted therein, the ends of the ferrulesabut each other to form a low insertion loss optical connection. Whenthe SC coupler is to be mounted to a wall plate, for example, the plateincorporates a housing member into which the couplers are inserted, thusthe body of the coupler extends outwardly from the surface of the wallplate.

In any such mounting of an optical fiber, there are certain restraintsthat must be observed which are aimed at protecting the fiber. Thus,there is a need for slack in the usually buffered optical fiber to allowfor handling and routing without incurring too sharp bends in the fiber.The Electronics Industry Association Spec. 568A calls for at least onemeter of fiber slack which may be stored on a storage spool, and aminimum bending radius of three quarters of an inch (3/4"). Thus, anywall mounting for optical fiber must be capable of meeting theseconstraints, which is difficult to realize where space is at a premium.These constraints on the optical fiber mode of connection have,apparently for the most part, deterred efforts to realize a universalfaceplate flush mounting arrangement for both electrical and fiberconnectors, especially where it is necessary or desirable to use theNEMA standard outlet box as a part of the outlet assembly.

Because of the rapidly growing use of both optical fibers and electricalwires and cables in the same milieu, attention has been directed moreand more to the realization of some form of universal connector oroutlet. There is in the prior art, for example, an arrangement forconnecting both electrical wires and optical fibers to an outlet boxwhich comprises a box or container consisting of a base plate and acover plate, with the base plate adapted to be mounted on the front ofthe outlet box. The base plate provides for snap-in SC and ST connectormodules (couplers) oriented vertically and opening toward the bottomsidewall of the faceplate. Within the volume defined by the base plateare pins and flanges for coiling the optical fibers within the volumewith an acceptable bend radius. The faceplate has provision for housingelectrical jacks wherein the wires therefrom are passed directly throughthe container to the outlet box. When assembled and mounted in place,the optical fiber connector modules are not readily visible andconnection thereto is apparently achieved by feel. The cover isremovable only by unscrewing and thus, ready access to the modules isnot easily realized. The fiber is coiled somewhat loosely within thecontainer and not well secured therein, and is stored on the room sideof the wall, without the protection of the wall against damage. Thus,the prior art arrangement leaves much to be desired in overcoming thevarious problems encountered with universal connecting assembliespointed out heretofore.

SUMMARY OF THE INVENTION

The present invention is a flush mounted universal outlet having ahinged faceplate primarily for use in customer premises, wherein bothelectrical and optical connections are easily made, and which meets theprotective restraints specified for optical fibers.

In the following discussion and claims, the term "cable" is usedgenerically to include insulated wires and individual optical fibers,preferably buffered.

The invention, in an illustrative embodiment thereof, comprises a flushmounted wall plate adapted to fit to or mate with, a standard outletbox. The wall plate has one or more telephone type modular jacks,although other types of connectors, such as coaxial connectors, may beused in place of or in conjunction with, modular telephone jacks. Inaddition, the plate has mounted thereon an optical duplex fiber couplerbody for receiving, at the front of the wall plate, first and secondoptical fiber connectors, preferably, but not necessarily of the SCtype. The body is mounted on the plate, or integral therewith, such thatthe receptacles therein for receiving the connectors are oriented at anangle to the plane of the wall or faceplate. Such angular orientationeliminates, to a large extent, any possible physical interferencebetween the modular telephone jacks and wires and the optical fiberconnectors and connected fibers, thereby providing sufficient room forthe jacks and the connectors to be independently inserted and removed.In addition, as will be apparent hereinafter, such angular orientationresults in the connectors, when in place, projecting downward at anangle instead of projecting straight out from the wall or faceplate,which latter is an orientation in which they can be easily damaged by anaccidental impingement from, for example, people or moving furniture orapparatus. The orientation of the couplers and connectors makes themclearly visible to one inserting or removing connectors, thus greatlyfacilitating such insertion and removal from the room side of the wall.The angular orientation also makes the assembly more compact so that aslidable protective cover or hood, designed to mount to the wall orfaceplate, covers both the optical fiber connectors and the electricalconnectors. The slidable cover protects the connectors and couplers inuse, and can be slid up or removed to provide access to the couplers.

In a preferred embodiment, the faceplate comprises a first, lowerportion which is adapted to be mounted to the front of the outlet box,and a second, upper portion which is pivotally mounted to the firstportion. The second portion is, like the first portion, adapted to bemounted to the front of the outlet box. Thus, the faceplate, in use, issecurely mounted to the outlet box. However, when it is desirable toaccess the rear of the faceplate, or the interior of the outlet box, forany reason, the upper portion of the faceplate may be disconnected fromthe outlet box and pivoted forward and down, thereby providing thedesired access to the outlet box and the rear of the faceplate.

The front of the faceplate is provided with substantially L-shapedaligned members which define tracks for receiving first and secondopposed flanges on the hood or cover so that it may quickly be slid intoplace over the faceplate to protect the various connectors. Thus, thecover can be easily removed or slid up from its position covering thefiber connectors for access to the connectors, which, being at an angle,are both visible and accessible to one removing or inserting aconnector.

At the rear of the faceplate is mounted a means for guiding and storingthe optical fibers that lead from rear SC connectors, which are insertedin the rear of the duplex coupler. The guiding and storing meanscomprises a storage spool having guide and retaining members thereon forreceiving, holding, and storing the fibers from the rear mountedconnectors. Projecting from the surface of the spool in the preferredembodiment is a mounting member in the form of a plate having, at thedistal end thereof, the male portion or member similar to a telephoneconnector plug, which is snap fitted into a receptacle in the wall plateby means of one or more resilient tabs. Thus, when the male member issnapped into place on the face or wall plate, the storage spool issecurely mounted thereto. The mounting plate also has, intermediate itsends, a curved fiber guide flange for guiding the fibers from the rearmounted connectors to the storage spool, thereby eliminating to a largeextent the possibility of fiber kinking, as well as minimizing anyunsupported lengths of fibers or slack. The storage spool can alsofunction as a storage member for electrical wiring from the rear mountedconnectors, especially when the wall plate is used with electricalconnection and couplers only.

As will be apparent hereinafter, the storage spool and support plate aredimensioned so that they readily fit within the outlet box when the wallplate is affixed thereto. Also, when the hinged wall plate is swungforward for access to the rear thereof, the spool and mounting plateswing clear of the outlet box without any interference or likelihood offiber damage.

The numerous features and advantages of the present invention will bemore readily apparent from the following detailed description, read inconjunction with the accompanying drawings.

DETAILED DESCRIPTION

In FIG. 1 there is shown the flush mounted wall plate assembly 11embodying the principles and features of the present invention. The wallplate assembly 11 is adapted to be mounted on a wall 12 shown indashed-dot lines in an opening having mounted therein, on the rear sideof wall 12, a standard NEMA electrical outlet box 13, shown in dashedlines.

As discussed hereinbefore, any connector or outlet mounting shouldprovide as much protection as possible to the fiber, especially thatportion of the fiber that is stored in accordance with the ElectronicsIndustry Association Spec. 568A. At the same time, the mounting shouldbe capable of providing ready access to the stored fiber, and should beconfigured to provide ready and preferably visible connection theretowithout the necessity of partially disassembling the mounting. Inaccordance with the principles of the invention, these criteria are metby the wall plate assembly 11 which comprises a flush mounted wall plate14 having a lower portion 16 and an upper portion 17 which is pivotallymounted to lower portion 16 by means of a pivot pin 18. Lower portion 16has a centrally located opening 19 into which a mounting screw (notshown) is inserted and which passes through a corresponding hole in thewall 12 and screws into a threaded mounting hole in outlet box 13. Inthis way, lower wall plate 16 is affixed to the wall 12 and the outletbox 13. In like manner, upper wall plate portion 17 has an uppermounting hole near the upper end thereof for receiving a mounting bolt(not shown) thereby securing upper portion 17 in place. As will be moreapparent hereinafter, when the upper mounting bolt is removed, portion17 of wall plate 14 can be swung forward and down, pivoting by means ofpin 18, to provide access to the rear of upper portion 17.

Mounted to the rear of upper wall portion 17, in a manner that will bemore clearly explained hereinafter, is a fiber storage spool 21 whichcomprises a cylindrical member 22 having a radius of curvature of itsouter surface 23 of at least three-quarters of an inch (3/4"), which isthe minimum recommended radius for fiber curvature specified in theaforementioned Electronics Industry Association Spec. 568A. Thus, whenthe fiber to be stored is wound on spool 21, the minimum radius for thefiber is no less than three-quarters of an inch (3/4"), and the fiber isfirmly supported on the surface 23 of spool 21. Spool 21 has radiallyextending tabs 24 at the ends thereof and fiber locating fingers 26 forinsuring that the fibers wound thereon to not slip off of the spool 21or become entangled. Spool 21 and an integral mounting arm 25 are sodimensioned that when upper wall plate portion 17 is swung upward intoits operative, vertical position, they enter outlet box 13 without anyinterference, and, when upper portion 17 is affixed in place, aresubstantially completely protected within box 13, behind wall 12.

Extending from the front face 27 of upper portion 17 is a protuberantmember 28 having a front face 29 oriented at an angle to the plane offront face 27. As shown in FIG. 1, the front face 29 is at an acuteangle to the front face 27 and hence, to the plane of the wall plate 14.Face 29 has first and second apertures 31, only one of which is clearlyshown in FIG. 1, which are adapted to receive and hold first and secondduplex couplers 32, as shown. As will be apparent hereinafter, openingsor apertures 31 are so configured and dimensioned that, in place of oneor more of the duplex couplers 32, the female portion of the modulartelephone jack may be substituted.

Each duplex coupler 32 is adapted to receive two SC type connectors 33,only one of which is shown. It is to be understood that other types ofcouplers and connectors may be used, although the use of SC typeconnectors and couplers is preferred. Extending from the rear of theduplex coupler 32 are first and second SC connectors 34 and 36, with thefiber 37 from connector 34 extending over a fiber guide member 38,mounted on or integral with mounting arm 25, and the fiber 39 from 36extending directly onto the surface 23 of storage spool 21. Such anarrangement minimizes any slack or unsupported lengths of the fibers 37and 39, which keeping them separated, thereby avoiding tangling orinterference with each other.

Face 29 also has a third aperture 41 into which is fitted the femaleportion 42 of a modular telephone jack, as shown, and a fourth aperture43 for receiving the female portion 44. Face 29 also has a fifthaperture 46, as will be best seen in FIG. 2, for receiving a mountinglock (not shown), positioned on the distal end of arm 25 of the storagespool 21 for locking spool 21 in place at the rear of faceplate 14. Itis to be understood that the apertures 31,31,41 and 43 may be configuredin different ways to accommodate various types of connectors, however,the configurations shown in FIG. 1 are the preferred ones. All of theapertures, and the couplers mounted therein, are visible from the frontof faceplate 14 when it is mounted in place, thereby materiallyfacilitating the insertion and removal of the connectors from the front.

In order that the front of faceplate 14, when the plate is mounted inplace and the several connectors are inserted in their respectivecouplers, be protected, a cover or hood member 47, having theconfiguration shown, is provided. Cover 47 has first and second inwardlyextending mounting flanges 48 and 49 for slidably mounting cover 47 tothe front 27 of faceplate 14. The upper portion 17 of faceplate 14 hastrack defining L-shaped brackets 51 and 52 and the lower portion hasL-shaped brackets 53 and 54 which define the lower portion of the tracksfor flanges 48 and 49. In use, the flanges 48 and 49 are inserted intheir respective tracks and cover 47 is slid down along the tracks untilthe front face 27 and, more particularly, the connectors and couplers,are substantially completely covered. When access to the front or rearof wall plate 14 is desired, cover 47 can simply be slid up partially orcompletely to provide such access.

In all of the foregoing discussion, such terms as "up", "down", "above"and "below" as well as other terms of orientation are applicable to thefaceplate orientation shown in FIG. 1. Obviously other faceplateorientations are possible, even to the extent of the faceplate 14 beingmounted completely upside down, in which case the terms defining theorientation of the various parts would necessarily be different, but thepositions of the several parts would remain the same relative to eachother.

The flush mounted outlet assembly as shown and described in theforegoing is the subject of U.S. patent application Ser. No. 08/534,218filed concurrently herewith on Sep. 26, 1995.

The following discussion is intended to present a more detaileddescription of the several components of the assembly of FIG. 1.

Hinged Faceplate

In FIGS. 2 and 3 there are shown front and rear views, respectively, ofthe upper portion 17 of wall or faceplate 14, and in FIGS. 4 and 5,front and rear perspective views, respectively of the lower portion 16of wall or faceplate 14.

Faceplate 14 is preferably made of a suitable plastic material such as,for example, a polycarbonate-ABS blend, which is both hard and durable,and which can readily be injection molded. The upper portion 17 of plate14, as shown in FIGS. 2 and 3 comprises a substantially rectangularmember having at the lower end thereof, a mounting tang 56 having, atthe distal end thereof a pivot pin 18. As can be seen in the figures,one end of pin 18 has an enlarged portion 57 which is tapered to a point58 and the other end of pin 18 also is tapered to a point 59. Tang 56has aperture 19 therein through which a mounting screw passes. Extendingsubstantially parallel to the sides of plate portion 17 are the L-shapedbrackets 51,51 and 52,52, which, as pointed out hereinbefore, definetracks for the flanges 48 and 49 of hood 47 so that the hood 47 may beslid down over the front face 27 of portion 17 and, when in its "down"position, held in place. A mounting boss 61, having an aperture 62therein, is located along the longitudinal center line of portion 17,with the center of aperture 62 being spaced from the center of aperture19, a distance equal to the tapped mounting holes in the standard NEMAoutlet box. Extending upward from box 61 is a stop lug 63 which, as willbe more apparent hereinafter, functions as a stop for hood 47.

Protuberant member 28 has, in the front face 29 thereof, which isstepped, as best seen in FIG. 1, to produce an upper flat portion 64 anda lower flat portion 66, first and second apertures 31,31 in the lowerportion 66, each of which is dimensional to receive a duplex coupler 32,as best seen in FIG. 1. The upper flat portion 64 has third and fourthaperture 41 and 43 for receiving the female member 42 and 44 of a pairof telephone jacks of standard configuration. The openings 31,31 arealso dimensional to receive, where necessary, the female members oftelephone jacks instead of the duplex couplers. Located above opening 43is a fifth aperture 46 which has a configuration similar to the femaleopening in a telephone jack for receiving a mounting lock on the storagespool 21 to lock the spool 21 to the rear of faceplate 14, as will beexplained more fully hereinafter.

In FIGS. 4, 5 and 7, the lower portion 16 of faceplate 14 is shown, towhich, in use, the upper portion 17 is pivotally mounted. Portion 16 hasfirst and second side sections 67 and 68 joined by a web member 69.Member 69 has a centrally located aperture 71 having an apertured floorportion 72 which has a smaller aperture 73. Aperture 73 is sufficientlylarge to allow passage of the shank of a mounting bolt, but not the headthereof. As a consequence, when member 16 is mounted in place and tooutlet box 13, the head of the bolt bears against the floor 72 ofaperture 71. As pointed out in connection with FIG. 1, member or portion16 has L-shaped brackets 53 and 54, which, together with brackets 51 and52 on member or portion 17, define the tracks for the flanges 48 and 49of the hood 47.

Web 69, which is not as long as either side 67 or 68, forms therewith acentrally located opening 74 which is further defined by spaced ribs 76and 77. The spacing of ribs 76 and 77 is slightly greater than the widthof tang 56 so that, when the faceplate is fully assembled as seen inFIG. 1, tang 56 is restrained from lateral movement by the ribs. Theribs define the narrowest portion of opening 75, which has angled sidemembers 78 and 79 extending from the front of the back of member 16 or,as viewed in FIG. 4, from top to bottom. On the sides of opening 75 arepin receiving slots 82 and 83, the inner ends of which have the ribs 76and 77 respectively, extending across the top, as seen in FIGS. 4 and 5.The bottom walls 80 and 81 of slots 82 and 83 are radiused at 84 and 86as shown, and the undersides of ribs 76 and 77 are sloped and radiusedas best seen in FIG. 5.

In order to attach member 17 to member 16, member 17 is swung down belowmembers 16 to an orientation shown in dashed lines in FIG. 7 where theangle of orientation relative to member 16 is preferably greater than180°, and by dashed lines in FIG. 4. Because of the sloping surfaces 78and 79, tang 56 can be moved laterally inasmuch as it is at the widestportion of the opening 74. Thus, tang 56 can be shined to the left, asviewed in FIG. 4 until the tip 59 of pin 18 dears the radiused portion84 and the small end of pin 18 enters slot 83, passing under rib 77.Tang 56 is then shifted to the right as viewed in FIG. 4 until tip 58 ofpin 18 clears the radius 86 at which time tang 56 is moved toward itscenter position, thereby inserting the large end of pin 18 into slot 82,passing under rib 76. Upper portion or member 17 is then rotated aboutthe axis of pin 18 in the direction of the arrow A. As member 17 isrotated, the width of opening 74 becomes increasingly smaller for tang56, and it is cammed by the sloping portions 78 and 79 toward itscentral position. Thus, lateral movement of tang 56 is increasinglyrestricted, and the ends 58 and 59 of the pin 18 cannot slip out of therespective slots 82 and 83. During the initial introduction of pin 18into opening 74 the sloping portions of the undersides of ribs 76 and 77function as guides to assist in centering the pin axis along thecenterline or axis of the slots 82 and 83. Continued rotation of member17 in the direction of arrow A, as shown in FIG. 6, brings it intovertical alignment with lower member 16, as best seen in FIG. 1, atwhich time it and member 16 can be affixed to the outlet box 13. Whenhood 47 is slid into place with the L-shaped brackets 51, 52, 53 and 54holding flanges 48 and 49 in place, lower and upper portions 16 and 17are locked in place, hence, even if the bolt for fastening the upperportion 17 to the box 13 should work loose or were missing, the plate 14would still be flat against the wall. When access to the rear of upperportion of member 17 is desired, hood 47 is removed and pivoted in thedirection of arrow B, as discussed hereinbefore. Because of theconstruction of member 16, mainly opening 74, slots 82 and 83, ribs 76and 77, sloped surfaces 78 and 79, and pin 18, upper portion 17 wouldhave to be pivoted down past the vertical to at least the position shownby the dashed lines before there would be any possibility of the pivotpin 18 slipping out of its slots 82 and 83. Inasmuch as the assembledwall plate 14 is flat against the wall, it would be impossible for it tobe swung past the vertical, hence there is no danger of an accidentaldetachment of upper portion 17 from lower portion 16.

Storage Spool

Storage spool or drum 21 is shown in perspective in FIG. 8 and in planand elevation views in FIGS. 9 and 10, respectively. Spool 21, which ismade of suitable material such as, for example, a polycarbonate-ABSblend, comprises a cylindrical member 22 having a longitudinal axis, anouter surface 23 which has a radius of curvature of three-quarters of aninch (3/4") or more, thus insuring that optical fibers, preferablybuffered, wrapped and stored thereon will have a minimum bend radius ofthree-quarters of an inch (3/4") which, as pointed out hereinbefore, isthe minimum recommended radius for fiber curvature specified inElectronics Industry Association Spec. 568A. On each end of the cylinder22 are angularly spaced radially projecting retaining tabs 24, with thetabs on end being angularly offset from the tabs on the other end, asbest seen in FIG. 10. Also, as can be seen in FIG. 10, one of the tabs24 closest to the wall plate when the spool is mounted thereon, has anangled or beveled portion 84 which facilitates winding optical fibersonto the spool. The tabs 24 perform the primary function of preventingfibers wound on the spool from slipping off at the ends thereof.Centrally located between the ends of the cylinder is a mounting arm 25integral with cylinder 22. Arm 25 has a first divider septum or wall 86at its proximal end which, in effect, divides cylinder 22 into twostorage areas. Extending from wall 86 is an elongated arm 87 which hasat the distal end thereof a spring latch mounting and locking member 88which is adapted to fit within the aperture 46 and locked therein bymeans of cantilever spring 89 in the same manner that the male member oftelephone jack locks into the female member. As can best be seen in FIG.9, arm 87 is offset from wall 86 in order that member 88 is aligned withthe opening 46 in plate 17 while maintaining the spool in a centralposition.

Mounted on or integral with the dividing wall member 86, and extendingoutward therefrom on either side is an arcuate fiber guide member 38. Ascan be seen in FIG. 1, guide member 38 is used to maintain separationbetween the fiber from connector 34 and the fiber from connector 36while providing support from the fibers, thereby minimizing slack fiber.In practice, the fiber from connector 34 is passed over guide member 38and supported thereby, and the fiber from connector 36, the end of whichis close to surface 23, is passed under guide 38, and the fibers arethen wound on spool 22 for storage and to provide the required maximumof one meter of excess fiber, as discussed hereinbefore. Centrallylocated on spool 22 and extending radially therefrom are first andsecond separating walls 92 and 93 from which extend fiber locating andretaining fingers 26,26 which are substantially parallel to the axis ofcylinder 22 and spaced from surface 23. When the fibers are wound ontocylinder 22, the walls 92 and 93 assist in maintaining separation of thefibers and the fingers 26 function to hold the fibers on or close tosurface 23, thereby minimizing or preventing any loops of slack fiber.

The dimensions of the spool 21 and its mounting am 25 are such that,when the spool is mounted to the rear of upper portion 17 of hingedfaceplate 14, there is no interference between spool 21 and the walls ofthe outlet box 13, either when the spool is enclosed therein or whenfaceplate portions 17 is pivoted outwardly. The enclosing of the spoolwith the fibers wound thereon adds another order of protection for thefibers. Not only are the fibers protected by being behind the wall andhence isolated from high traffic on the room side of the wall, but thefibers are also protected by the standard outlet box 13. Substantiallyoptimum dimensions for the spool assembly are a radius of curvature ofsurface 23 of no less than three-quarters of an inch (0.75"), the lengthof cylinder 22 is approximately one and six-tenths inches (1.6"), walls92 and 93 are approximately one-quarter of an inch (0.25") high andtwelve one-hundredths of an inch (0.12") thick, and the distal end ofarm 25 is approximately two and fifty-nine one-hundredths inches (2.59")from the central axis of cylinder 22. These dimensions are given herefor illustrative purposes only and, although they have been found to be,in practice, preferred, it is to be understood that changes to one ormore of these dimensions may be made so long as the spool assembly stillfunctions in the manner intended, as set forth in the foregoing. Also,it is to be understood that while the mounting jack arrangement 88 and89 has been found to function well and is to be preferred, other typesof mounting arrangements, including permanent mounting, might be usedprovided the spool assembly retains the functional advantages set forthhereinbefore.

The spool assembly as set forth in the foregoing is the subject matterof U.S. patent application Ser. No. 08/533,156 filed concurrentlyherewith.

Protective Hood

The protective hood 47 of FIG. 1 is shown in detail in FIGS. 11 through14. As discussed in the foregoing, hood 47 is removably mounted on thefront wall plate 14 when the plate is in its assembled and mountedcondition, and can either be partially slid up to provide an openposition for access to the various couplers 32, 32, 42 and 44 or can becompletely removed when it is desired to pivot upper portion 17 of thewall plate 14 relative to lower portion 16.

In the following discussion, such terms as "lower"and "upper" refer tothe hood relative to the face or wall plate 14 being mounted in anupright vertical position. Obviously there can be other orientations ofthe face or wall plate 14, whereby the terms "lower" and "upper" shouldbe read as defining the orientation of the hood relative to the face orwall plate 14 in whatever orientation it may have.

Hood 47, which is an elongated substantially hollow member, and whichmay be made of any suitable light weight semi-rigid material, such as,for example, a polycarbonate-ABS blend, has a U-shaped open lower end96, as best seen in FIG. 13. The ends of the U-shape terminate ininwardly extending flanges 48 and 49 each of which has a slight taper 97at the open end, as best seen in FIG. 12, for ease of insertion of theflanges 48 and 49 under the lips of the L-shaped track forming brackets51, 52, 53 and 54 as seen in FIG. 1. Hood 47 has an upper end 98 (righthand end as shown in FIGS. 11, 12, and 14), which is flat and orientednormal to the centerline 99 of hood 47, as best seen in FIG. 14. End 98is joined to the front end or lower portion 96 of hood 47 by a slopedplanar surface 101 which extends, as shown, from a point above lower end96 to the end 98. A stop member 102 is currently located, preferablycentrally, on the interior side of flat end 98, and, in use, functionsto limit the downward movement of hood 47 over face or wall plate 14 bybutting against stop member 63 which is best seen in FIG. 2, therebyestablishing the closed position of the hood.

In order that hood 47 may be easily moved in the tracks formed by thebrackets 51, 52, 53 and 54, the facing tips of the flanges 48 and 49 atthe open end 96 are spaced apart a distance B which is slightly greaterthan the distance A between the tips of the flanges at the closed end98. This differential spacing, plus the tapers 97.97 on the lower endsof the flanges, make insertion of hood 47 onto the tracks and movementtherealong relatively easy so that any one desiring to remove or installthe hood can do so with a minimum of effort.

Protective hood 47 may be made opaque, transparent, or translucent, andmay be, if desired, colored to match a room decor for example, as mayface or wall plate 14.

The protective hood 47 is the subject of U.S. patent application Ser.No. 08/533,156 filed concurrently herewith.

The flush mounted universal outlet assembly of the invention and theseveral components thereof provide a large measure of protection of thevarious connectors and associated wires or fibers, both by means of theprotective hood and the unique configuration which places the storedportions of the optical fibers behind the room wall and within theoutlet box. The assembly provides ready, visible access to allconnectors on both the front and the rear of the wall plate, and isdesigned to mount to a standard outlet box. No special tools arerequired for assembling the several parts, all of which are readilyseparable from each other and yet which form a unitary whole.

In concluding the detailed description it should be noted that it willbe obvious to those skilled in the art that many variations andmodifications might be made to the preferred embodiment withoutsubstantial departure from the principles of the present invention. Allsuch variations and modifications are intended to be included hereinwithin the scope of the present invention, as set forth in the followingclaims.
